that have become iconic in america's bizarre and shameful epidemic of gun violence. >> reporter: public outrage over the massacre has also emboldened members of congress to challenge the power of the gun lobby. >> the political power is much like the wizard of oz. they're bullies. and what's most important is, they really don't represent their membership. the members are overwhelmingly in favor of responsible use of guns and responsible rules. >> reporter: feelings are running very high after this tragedy. of course, there's been a lot of talk of a turning point. the president today will announce that he's putting vice president biden in charge of a process to look at possible new legislation. but, look, change doesn't happen quickly in washington. there have been about a dozen attempts to bring back the assault weapons ban. they've all failed in congressional committee. and the national rifle association spent $17 million this year to influence legislation and public opinion. it'll be looking out for its interests long after the outrage subsides. charlie, norah? >> bill plante, thanks.

slaughtered in america. >> reporter: he's now open to the possibility of banning large magazines. after getting a call from president obama today, manchin put out a statement saying "we must work together to keep our precious children safe." in congress, three democrats with long histories as gun control advocates are taking the lead with proposals to ban both military-style assault weapons and high-capacity magazines. show me how this works, how quickly can you change a magazine? >> it's out; it's in. >> reporter: but at a northern virginia gun store today, this instructor said banning large magazines like this one with 30 rounds is futile. >> he could have had ten-round magazines and changed those just as quickly before police got there and it wouldn't have made one difference in the carnage that he caused. >> reporter: he wanted to show us the 60-round magazine, scott, but he couldn't because the store has sold out its entire inventory of about 2,000 large magazines in just the past four days. he said gun owners are snapping them up because they're worried they will soon be banned. >
